VOB to MPEG2

Is there anyway to convert VOB files to MPEG2 the reason i want to do this is that i have some old home video footage on DVD and i need to make some more changes to it in video studio 9 however it will not let me edit VOB files and i dont have the original footage.

Yes. VOB files are essentially MPEG2 encoded video. Something like TMPGenc will do the conversion.

Howver, I would suggest you first try simply changing the extension to .mpg from .vob (assuming they are not encrypted this should work). Alternatively transcode to DV as described in the FAQ (as MPEG editing isn't recommended):
